There is something deeper than just our surface beliefs that partly dictates what those beliefs will be. I think this is more reflective of what we mean by a worldview.
If you really want to get a grasp on what a Christian worldview is, you’re going to have to devote yourself to reading a little philosophy and literature, with an emphasis on the history of ideas. I will say, however, that there are some great writers and great resources out there to get you started on this endeavor. What follows are the books I have recommended to my youngest son, who is now a philosophy major at the University of Kentucky. I think he would tell you that they have benefited him a great deal. For the most part they are books that simplify a lot of the main issues involved in the question of why we think what we think. But, also for the most part, they avoid oversimplification.
